This remarkable pen/pencil pen is currently a top seller in Asia. It has EVERYTHING. It's a 0.7 mm red, blue, black, green color ballpoint pen AND a 0.5 mm mechanical pencil! It's not boring looking like the pens in the US and it's amazingly compact. You can barely tell it's a multi-function pen.
The clip on the pen is a "clip on", meaning you can press it open to clip on to thicker objects such as a binder without worrying about breaking it.
